Replace soundtracks, retouch videos, trim without quality loss, using VirtualDub

VirtualDub helps you get video into your computer and edit. Integrated volume meter and histogram for input level monitoring. Real-time downsizing, noise reduction, and field swapping.

The program lets you remove and replace audio tracks without touching the video.

Features: Extensive video filter set, including blur, sharpen, emboss, smooth, 3×3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace, and threshold. Decompress and recompress both audio and video.

Remove segments of a video clip and save the rest, without recompressing. Adjust frame rate, decimate frames, and 3:2 pulldown removal. Preview the results, with live audio. You can take a captured clip, trim the ends, clean up some of the noise, convert it to the proper frame size, and write out a better one.
